LOCALLY SEMIUNIVERSAL FLAT DEFORMATIONS OF ISOLATED SINGULARITIES OF COMPLEX SPACES

Mathematics of the USSR-Izvestiya, 1969
In this study we construct the minimal locally semiuniversal deformation of a normal isolated singularity x0 X0 for which Ext²O(X0)(Ω(X0), O(X0))x0 = 0, where Ω(X0) is the sheaf of germs of one-dimensional holomorphic forms in the complex space (X0, O(X0)).

Fast Automatic Localization of Epileptic Seizure Onset Zones Using Complex Morlet Wavelet Transform-based Singular Value Decomposition

2018 37th Chinese Control Conference (CCC), 2018
A new method for localization of epileptic seizure onset zones (SOZs) is proposed, which uses the Shannon-entropy-based complex Morlet wavelet transform to extract a satisfactory time-frequency feature of high-frequency oscillations (HFOs). The singular value decomposition and the K-medoids clustering algorithm are employed to extract effective ...

Synthesis and Structural Characterization of the One-Dimensional [Cu(3-Clpy)₂(N₃)₂]_n Complex (3-Clpy = 3-Chloropyridine):  A Singular Ferrimagnetic Chain with Local S_A = S_B

Inorganic Chemistry, 1998
Ferrimagnetic behavior has been found for the one-dimensional azido-bridged compound [Cu(3-Clpy)2(N3)2]n, in which 3-Clpy is 3-chloropyridine.

Local complex singularity exponents for isolated singularities

2004
In this thesis, I studied the stability of local complex'singularity exponents (lcse) for holomorphic functions whose zero sets have only isolated singularities. For a given holomorphic function f defined on a neighborhood of the origin in C[to the power of]n, the lcse c[sub]0(f) is defined as the supremum of all positive real number [lambda] for which

Momentum eigenfunctions in the complex momentum plane. II. Relation of secondary singular points to one-electron, local, potential functions

The Journal of Chemical Physics, 1979
In a previous paper [J. Chem. Phys. 64, 4375 (1976)] it was shown that the points P=±i√−2E in the complex momentum plane (E is the one-electron energy eigenvalue) are singular points of the one-electron momentum eigenfunction obtained from a one-electron local potential function. In the present research a whole series of additional (secondary) singular
